 ### ppmRate
 Proc per minute. If 0 the value will be taken from DBC.
 
+ppmRate is a rate and therefore will not be guaranteed to prox X amount of times per minute. ppm is calculated by this formula
+```
+((WeaponSpeed * PPM) / 600.0f);   // result is chance in percents (probability = Speed_in_sec * (PPM / 60))
+```
+
 ### CustomChance
 If non-zero, chance for spell to trigger.
